The Paerau Gorge Multipurpose Scheme
The Paerau Gorge Power Scheme is part of a multipurpose scheme supplying irrigation water and electricity to the Central Otago region of the South Island of New Zealand. This paper describes...
Economic Analysis of Low Head Hydropower Projects
A typical low head hydropower project is described and used as an example of the effect of tailwater on power generation. The discharge characteristics of upstream facilities, pool regulation...
The PowerBarge?Portable Hydro for the Third World
The PowerBarge concept consists of a floating intake, siphon penstock, and floating generating station for use at new or existing low-head dams. Apart from access, mooring facilities,...
Optimization of Low Head Hydro Equipment
In this paper, we will limit our purpose to the presentation of the different types of turbines that CE/Neyrpic proposes for low head power plants, for run of the river operations. We...
Small Kaplan Versus Tubular and Francis Turbines
Mossefossen Power Plant is situated in the centre of the small town Moss in the southern part of Norway. Water flows from an existing dam through a 9 m**2, 175m long tunnel to the powerhouse...
Design Criteria for Generators in Low-Head Hydro-Power Plants
Principal characteristics and design features of such generators are discussed and options and preferences in their selection mentioned. Effects on inertia constant, efficiency, reactive...
Index Testing?Relative Turbine Performance
The Index method of testing hydraulic turbines consists of making a test in which the value of power output and head are measured and in which the quantities of water and velocity head...
Arch Dams for Small Hydroelectric Sites
Approximate formulas are developed for the design of small arch dams. These designs, although conservative, frequently allow for economies over other dam types. Considered are: an approximate...
Control System Design Considerations for Small Hydro Projects
This paper deals with the philosophy that must be embraced when specifying a fast track small hydro project. The major areas discussed are: the role of control systems in the context of...
Changing Stability Criteria: Effect on Older Dams
Many of the dams on the Georgia Power Company system were designed and constructed in the early 1900's. Changes that have occurred in stability criteria since construction...
Dynamic Analysis of Existing Tarbela Intake Towers
According to general practice at the time of the design, the pseudostatic method of applying earthquake loading was used. The basic acceleration was 0. 1g. A post-construction seismological...
Rapid Filling of Reservoirs
The rate of filling a reservoir, particularly for the first time, is governed by various factors. While economic considerations may favor rapid filling of reservoir to operational levels,...
An Overview of Hoover Dam Tunnel Spillway Damage
The Hoover Dam tunnel spillways have provided the Bureau of Reclamation hydraulic laboratories with new and continued opportunities for applied research. During the peak years of the Boulder...
Safety of Dams Activities in the Bureau of Reclamation Lower Colorado Region
In the Lower Colorado Region of the Bureau of Reclamation (BuRec), there are presently eight BuRec dams and one Bureau of Indian Affairs dam being modified or studied for modification...
Application of Computer Aided Design and Analysis Tools for Upgrading Existing Power Plant Equipment
This paper presents examples where state-of-the-art computer aided design and analysis techniques have been applied to upgrade hydraulic performance and structural reliability of existing...
Preventing Fish Mortality at a Large Pumped Storage Plant
A field study program was initiated at the Truman Project to obtain a better understanding of which fish species in the tailrace area would be most susceptible to turbine passage, determine...
Galt Energy's Inverted Siphon System
Galt Energy Systems' involvement with attempting to standardize the civil component began with studies at small remote sites in Northern Ontario. The system design evolved...
Hydro System Enhancement: TVA's Comprehensive Hydropower Program
The Tennessee Valley Authority's Comprehensive Hydropower Program is systematically identifying opportunities for increasing hydroelectric generation in five areas: small...
Seismic Isolation System for a Floating Dry Dock
The seismic isolation system consists of two dolphins, each a relatively large-diameter cantilevered steel pipe pile anchored in Franciscan rock, and buffered connections to the floating...
LRFD Format for Transmission Structures
The structural design of high voltage electric transmission lines in the US is usually governed by the National Electrical Safety Code (NESC). A simple reliability-based Load and Resistance...
